The TX side of the project is still fairly primitive--they have a
hand-coded flow-graph that implements an APCO-25 4-level
FSK modulator, using an *audio* sink, and then carefully plugging the
audio into the guts of a physical radio, right at the [snipped]
Soundcard output direct into a TX
In the case of a real flow-graph, taking real data in at
4800symbols/second, going to a real USRP transmitter, will it still
run in fits and starts or will it do the right thing??
It will do the right thing, assuming that all blocks do the right
thing and compute as much output as they
